【発明の詳細な説明】
本発明は、電槽と蓋とを熱溶着してなる蓄電池とその製
造法の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a storage battery in which a battery case and a lid are thermally welded together, and a manufacturing method thereof.
従来、この種の蓄電池においては、第５図に示す如く電
槽（図示省略）の上端面に対応して蓋Ａの下面に溶着代
としての突条Ｂを設けている。Conventionally, in this type of storage battery, as shown in FIG. 5, a protrusion B is provided as a welding margin on the lower surface of the lid A corresponding to the upper end surface of the battery case (not shown).
しかしながら此の構造では成型上並びに組立上、必然的
に生じる電槽隔壁等の反りを考慮して、突条Ｂの巾を電
槽隔壁等の巾よりも広く設定しているため、蓋の肉厚が
部分的に不均等になってヒケＣを生じる欠点があった。However, in this structure, the width of the protrusion B is set wider than the width of the battery case partition wall, etc. in consideration of the warpage of the battery case partition wall, etc. that inevitably occurs during molding and assembly. There was a drawback that the thickness was partially uneven, causing sink marks C.
また電槽隔壁等と蓋下面の突条Ｂとを正しく衝合させる
ための手段として、第６図に示す如くカイトＤを設けた
蓋Ａ′も提案されているか、これによっても常に万全で

った。In addition, as a means for properly aligning the battery case partition wall, etc. and the protrusion B on the lower surface of the lid, a lid A' having a kite D as shown in Fig. 6 has also been proposed, and this also ensures complete safety at all times. However, in any case, there was a drawback in that it required a considerable amount of assembly effort to completely heat-weld the battery case and the lid.
本発明は、上記の欠点を一挙に解消せんとするものであ

６は端子を示す。First, in the figure, 1 is a battery case made of polyolefin synthetic resin such as polypropylene or polyethylene;
4 is a lid made of the same material as battery case 1, and 5 is a conventional protrusion B (see Figs. 5 and 6).
6 is a thermally welded part that is fused into one body, 7 is a hot plate, 8 is the upper end surface of the battery case 1 (see figure) ribs 9 attached to the upper surface of the hot plate 7 corresponding to the upper end surfaces of the partition wall 2 and the peripheral wall filter;
It is a suction cup for sucking and holding. Note that 10 in the figure
1 is the electrode plate group, 11 and 12 are the liquid inlet and terminal hole, respectively.
6 indicates a terminal.
次に、図示した本発明蓄電池の製造法について説明する

面５の被溶着部は、熱板７のリブ８によって溝状に溶融
される。Next, to explain the manufacturing method of the illustrated storage battery of the present invention, first, the electrode plate group 10 is composed by a conventional method, and this is placed in the battery case 1.
After inserting the battery case 1 into the battery case 1 and connecting the cells, the upper end surface of the battery case 1 and the lower lid surface 5 are melted with a hot plate 7 interposed as shown in FIG. At this time, the welded portion of the lower lid surface 5, which was flat as shown in FIG. 4, is melted into a groove shape by the ribs 8 of the hot plate 7.
引続いて熱板７を除去し、電槽１と蓋４とを相互に圧着
すれば、第１図及び第２図に示す如く前記両者を液密に
シールする熱溶着部６の形成された蓄電池が得られる。Subsequently, the hot plate 7 is removed and the battery case 1 and the lid 4 are crimped together to form a heat welded part 6 that seals the two liquid-tightly, as shown in FIGS. 1 and 2. A storage battery is obtained.

となり、従って肉厚の不均等にょるヒケがなく外観的に
も良好で且つ蓋４のコストも従来品に比し安価となる利
点を有する。As described above, the present invention thermally welds the upper end surface of the battery case 1 and the lower lid surface 5 from which the part to be welded does not protrude. Even if the bottom surface 5 of the lid is warped, the bottom surface 5 of the lid is melted corresponding to the top surface of the battery case 1.
By setting the width of the hot plate rib 8 to an appropriate size so that the size of Ex-Q during melting is commensurate with the size of Ex-Q of the battery case partition wall, etc., the battery case 1 and the lid 4 can be securely connected. Moreover, it can be easily welded. Moreover, the lower surface 5 of the lid has a protrusion B like the conventional one.
Since the lid 4 is not provided at all, the lid 4 has a substantially flat and simple shape, so there is no sinkage due to uneven wall thickness, and the appearance is good, and the cost of the lid 4 is lower than that of conventional products. It has the following advantages.
